The symmetry changes from a high-temperature cubic phase in a metallic state to low-temperature tetragonal phase in an insulating state. A significant characteristic feature is the absence of localized magnetic moment below TM-I. On the other hand, NiIr2S4 remains metallic down to 4.2 K without the structural transformation. We have systematically studied the structural transformation and electrical and magnetic properties of Cu1-xNixIr2S4. The variation of the metal-insulator transition with Ni concentration x is presented. A phase diagram between TM-I and x will be provided for the Cu1-xNixIr2S4 system. The TM-I varies drastically from 226 to 88 K with x from 0.00 to 0.13 and disappears around x=0.15. For 0.08&les;x&les;0.13, the cubic and tetragonal phases coexist below TM-I. For a high-temperature metallic phase, the value of the Pauli paramagnetic susceptibility increases monotonically with x, which shows dD(&epsiv;)/d&epsiv;<0 at the Fermi energy &epsiv;F, through the decrease of the free-electron number density, where D(&epsiv;) is the electronic density-of-state on the basis of a nearly free-electron model. By the introduction of a Ni ion to the A-site of CuIr2S4 in the spinel structure, whether the localized magnetic moment below TM-I arises or not will be discussed","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_79_link_17":{"attribute_name":"出版者版へのリンク","attribute_value_mlt":[{"subitem_link_text":"10.1103/PhysRevB.64.075106","subitem_link_url":"https://doi.org/10.1103/PhysRevB.64.075106"}]},"item_79_link_5":{"attribute_name":"室蘭工業大学研究者データベースへのリンク","attribute_value_mlt":[{"subitem_link_text":"近澤
